i was wondering if anyone knows how to do things like add weights to cloth? a pendant at the end of a ribbon would be an experimental example. i'm not even sure how to do rigid body dynamics, or where to start looking for information about it. so i'm really unsure about how you'd put the two together. but i'm sure it's possible.

I was trying to figure out how to combine rigid bodies and cloth some time back and eventually gave up, but that was a couple blender versions ago. If you figure it out I'd love to know, too.

ooooo. do you know how to do rigid bodies? because if you could give me a lead on that, i'm pretty sure i could get them both to work together. it shouldn't be any different than combining clothes and any other kind of controlling animation. i could tell you how to do that in a snap if you don't know how. if it's some other issue, like how fluids and cloth won't respond to each other, then i'm stumped. but the thing is i haven't been able to find a good rigid body tutorial.

Oof. It was a while ago, but you know, I think it was figuring out how to do rigid bodies at all that stumped me. I know it's possible because I've seen animations of dominoes falling... I think those might have used the game, engine, does cloth simulation work in the game engine?

ah! and that does explain my confusion. i wasn't looking at game information, thought that if there were soft body, fluid and cloth dynamics in a certain area, surely there was a way to set up rigid body physics there. i wonder if they're more integrated in 2.5? i'll let you know if i can find anything out.

I vaguely remember seeing that it might be in 2.5, but that was back when everything and the kitchen sink was going to be in 2.5, so I don't know if it made it.

You might want to check out the Book, Bounce, Tumble and Splash by Tony Mullen. Good book for many Blender sfx. also check out fairly new Blender Video web site.

It occurred to me that rigid bodies are really just stiff soft bodies, so I tried setting up the dominoes example using softbodies. I could get the first domino to collide with the second, but I couldn't get the second to fall. That's probably the way to get hard things to interact with cloth, though.

oh, that's brilliant! thanks for the tip!
